CIGAR-BUNCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 497,415, dated May 16,1893.

Application filed November 1. 1892. Serial No. 450,683.- (No model.)

To all whom it may concern..- Be it known that I, ADOLPH O. SOHUTZ,residing in Brooklyn, Kings county, and State of New York, have inventedan Improvement in Oigar-Bunching Machines, of which the following is aspecification, reference being had to the accompanying drawings,wherein- Figure 1 is a front elevation of my improved cigar bunchingmachine. Fig. 2 is a side elevation of the same, partly in section, theline 2-2 Fig. 1 indicating the plane of section.

1 Fig. 3 is a plan or top view of the same with part of the table brokenaway. Fig. 4 is an enlarged vertical cross-section on theline 4:4 Fig.3. Fig. 5 is an enlarged section across the treadle, the line 55 in Fig.6 indicating the plane of section. Fig. 6 is an enlarged detail verticalsection on the line 66, Fig. 5, showing the lower pivotal connection ofthe roller-carrying-frame. Fig. 7 is a similar vertical section on theline 77 Fig. 8, showing the upper pivotal connection of said roller.carrying-frame; and Fig. 8 is a detail horizontal section on the line 88Fig. 7.

The object of this invention is to produce apparatus for convenientlyforming tapering long-filler cigar bunches, and the invention consistsprincipally in the employment of a rolling-board having a convex curvedupper surface, the curve extending from front to back'of saidrolling-board so that the surface of said rolling-board is lower infront and lower at the back than in the middle. Said rolling-board alsois, when seen from above, of isosceles trapezoidal form,the two parallellines of which border the sides of the rollingboard, while the twoconverging sides of said trapezoid constitute the front and back edges.

' With this rolling-board I am enabled to em:

ploy a tapering roller which is adapted when rolled over the surface ofthe board (in an apron of course) to keep its axis always directed tothe point of convergence of the front and back edges of therolling-board, while at the same time said roller travels up and thendown over the curved surface of the rollingboard. By having the rollerduring its rotation describe an arc of a circle of which the point ofconvergence of the front and back edges of the table would be thecenter, I am enabled to roll the bunch of tobacco in the their movement.

apron to the desired taper. At the sametime the roller is forced to movethe bunch over the convex surface of the rolling-board,whereby I gainthe advantage that with a given length of rolling-board I obtain a morethorough rolling of the bunch, or, in other words, an actually increasedrolling surface for the bunch.

The invention also consists in peculiar mechanism hereinafter describedfor moving the roller, and in other details of improvement that will behereinafter more clearly pointed out.

In the accompanying drawings, the letter A represents the frame of mymachine. The upper part of this frame supports a table B, which at thesides and back is by preference embraced by ledges a. At its frontportion the table B is cut away to make room for the rolling-board C;yet this rolling-board may, if desired, be secured upon the surface ofthe table, in which case slots would be formed in the table alongside ofthe rolling-board to make room for the roller-carrying-arms and Therolling-board O is, as has already been stated, of isosceles trapezoidalform when inspected from the top, as clearly appears from Fig. 3, theconverging sides of said trapezoid being the front and backedges of saidtable, as shown. The said rolling-board when looked at sidewise as inFig. 2 and in section as in Fig. 4;, shows a convex surface, it beinglower at the front and at the back and highest in the middle.

I) is the roller for carrying the loop of the apron E that contains thebunch to be formed over the rolling-board. This roller D is hung inarmsb of a roller-carrying-frame F, which frame F is pivoted in the mainsupporting frame A. An examination of Fig. 1 will show that one leg d ofthe roller-carrying-frame F is longer than the other lege of said frame,but the pivots f g by which these arms are respectively connected to theframe A stand inclined toward one other, as very clearly appears fromFigs. 6 and 7, and so that aline drawn from one pivot to the other, asthe dotted line it in Fig. 1 indicates, will pass through the axes ofsaid two pivots; consequently the frame F when swung to bring the rollerD backward and forward over the IOO surface of the rolling-board 0 moveson the pivotal line it which is not parallel with the surface of thetable B, but, on the contrary, is inclined to said surface. It is veryclear, therefore, that. the rollercarryingframe F swinging on theinclined line It describes an arc of a circle of which theline his thecenter, and that consequently the roller I) is moved in the same are ofthe circle. Inasmuch,however, as the roller hangs in bearings in theroller-carrying-frame so as to occupy a substantially horizontalposition, which is at an angle to the inclined pivotal line 72, thenarrow end of the roller which is nearest the pivot 9 moves on a sharperarc than does the broader end of the roller which is nearest the lowerpivot On the curvature thus produced by the swinging of the horizontallylocated roller on the inclined pivotal line It the convex surface of therolling-board O is constructed. Thus I have shown how a curvilinearmotion is obtained for the rollerD by the vibration of therollercarrying-fame F. At the same time, however, the roller byfrictional contact with the apron on the rolling-board, revolves on itsown axis.

It will be observed from Fig. 3 that in the initial position the rolleris paralled with the inclined front edge of the rolling-board, and beinga tapering roller, it retains as it moves toward the back of therolling-board a direction which points to the line of convergence of thefront and back edges of said rolling-board. Thus a tapering roller suchas is shown and such as is used in this machine will have a rotationaround its own axis, a displacement from one inclination to anotherinclination corresponding to the two inclined edges of therolling-board, and a curvilinear motion which depends upon theinclination of th pivotal line h.

In Fig. 1 of the drawings the highest pivot g is shown about midwaybetween the top and bottom of the frame A; but it is evident that thesaid pivot g maybe elevated more or less, in which case the line ofinclination h will be correspondingly varied and the difference betweenthe curves described at the opposite ends of the roller correspondinglymodified. Thus I am able to produce with the assistance of a properapron E, which is fastened at both ends, a bunch having the desiredtaper, and to roll this bunch over an elongated surface of the convexrolling-board, until it may be received at the back end of saidrolling-board by a suitable bunch-receiver G of ordinary construction.The apron E is secured at its back end to the back end of therolling-board in any suitable manner, but its front end is fastened in aclamp H, which at i is pivoted to the rolling-board, or an extensionthereof, or to the table 13, or other part of the framing. This pivotedclamp II is provided underneath the rolling-board with an inwardly orrearwardly projecting armj having a step or downward extension 70, asshown in Fig. 2. The

roller-carryirig-frame F is provided with a frictional roller Z oranalogous projection which, when said frame F is swung backward, movesunder the lower face of the arm j until it strikes the step or set-off70, when, the frame F continuing, in its backward motion, said roller Zlifts the arm j, and thereby moves the clamp ll forward 1'. c. outward,thus stretching the apron E and tightening it on the bunch, which atthat time is already enveloped by the apron and on the convex portion ofthe rolling-board. Motion may beimparted to the frame F either by meansof handles m, with which it is provided, or by means of a treadle I, orby both handles and treadle. The treadle I is shown pivoted to the frameA and connected by a link it with the long leg (Z of the frame F. Inswinging the treadle on its pivot, it will by this link it cause thelong leg (Z of the roller-carrying-frame F to be swung, and thereby, infact, the whole frame F to be swung. The connections between the link aand the treadle and the leg at are by preference either or both slightlyslotted, or the holes for the connecting pins are slightly enlarged soas to avoid any strain which otherwise would be caused by thehorizontalvibratin g treadle engaging with the roller-frame that swingson the inclined line 7b. This onlargement is indicated by dotted linesin Fig. 5.

Although I have described the roller-board O as having the isoscelestrapezoidal form when examined from the top, it is nevertheless clearthat if the parallel sides of the trapezoid be made slightly curved, thesame final result would be obtained, and I therefore wish to have itunderstood that the expression isosceles trapezoidal form when appliedto this rolling-board would include the modification just mentioned.

It is quite clear that a bunch 0, Fig. 2, when enveloped in the fold ofthe apron by means of the advancing roller D, will find itself embracedin a tapering loop of the apron, and will continue in said tapering loopuntil it is finally delivered properly rolled in the bunchreceiver Gr.It is clear also that the apron E of this machine when inspected fromabove has the isosceles trapezoidal form already specified as the formof the rolling-board, or substantially the same, allowing, of course,for the difference in length between the apron and the rolling-board.

Having described my invention, what I claim, and desire to secure byLetters Patent, 15-- 1. The combination of the rolling-board 0 havingconvex upper surface and snbstantially isosceles trapezoidal form, withan apron E, and with a tapering roller D, and means substantially asdescribed for moving said roller, all as specified.
